The VPU kernel driver is already enabled in the BSP and is available at the following path: drivers/mxc/hantro_845/hantrodec_845s.c
If compiling the Yocto BSP, all the required VPU drivers and packages will be included automatically in the root filesystem. It is recommended to do the full build in Yocto to avoid any version mismatch.
After the build is complete, the generated .deb packages can be found in:
tmp/deploy/deb//
This directory will contain the .deb packages generated during the build process.
